NOTE: you can hide any coins that you don’t follow so they don’t show in the list. Click the far right tick box on coins you want to show up, so you won’t have to weed through the whole list every time. This is useful since many people only deal in a handful of currencies. Here I show how to do it if you only want to see BipCoin and Bitcoin. lol.:

Then, while on that page, double click on the “Show Address” of the currency you want to deposit.

Buy orders are the way to get the lowest price but it can take a day or two.

For immediate orders, I’ve click on the left on a price / amount I like and buy it on the spot. Or entered an amount to buy and buy it.

BUY ORDERS:
Randy adds: I set a buy order and overnight, half a dozen sellers came in and sold me chunks of my buy order. At the moment all but about 3% of it is complete. So I would say it went extremely well, considering the price I paid was so far below what people were asking over on the left hand “Sell Orders” box.

I think the trick is not to match a sell order in the left hand box, but to offer the highest buy price in the “Buy Order” list on the right. Sellers just show up and grab the best deal they can get on the spot.
